Warriors forward Tohu Harris has revealed more about the emotional toll of leaving his wife and three-year-old son in New Zealand to travel to Australia in a bid to get the NRL season restarted on May 28.

The Kiwi outfit flew to the New South Wales town on Sunday not knowing how long it would be until they saw their families again.

Training resumed in small groups on Wednesday, but the harsh realities of an extended period of time away from their loved ones is already starting to sink in.

"It was very hard saying goodbye. My little three year old kept asking to come with me," Tohu Harris said on Wednesday.

"My wife struggled really badly the night before and that morning with the thought of me leaving and not knowing we can see each other.

"It made it very hard to get on the plane - it's still hard being here.

"I saw a video of my son just before we got on the call just asking for me to come home and play with him.

"It's very hard to be here."

The Warriors will remain in quarantine in Tamworth for the next two weeks until the season restarts on May 28.

Harris said he's filling in his free time with extra training sessions and plenty of calls back home, while constantly reminding himself why he's made the sacrifices he has.

"We don't really have other options at the moment, there's a lot of people relying on us to be here so they can get income and help their families," he said.

"That's what I've gotta keep reminding myself of why I'm here.

"I'm trying to fill in my time with extra trainings or stretching and the rest of the time I'm pretty much on a video call back to my wife and son just to talk with them and be with them.

"That's how I'm filling my days at the moment.

"I've just gotta keep reminding myself why I'm here. There's a lot of people relying on us being here. We've got hard working staff that rely on us being here to earn an income. If being here helps them, that's something I have to do."
